B Series circuit breakers Carlingswitch magnetic circuit breakers are current sensing devices employing a time proven hydraulic
magnetic design. These precision mechanisms are temperature stable and are not adversely affected by temperature changes in their
operating environment. As such, derating consideration due to temperature variations are not normally required and heat induced
nuisance tripping is avoided


• Trip free mechanism, a safety feature which makes it possible to manually hold the contacts closed during overcurrent or fault condition
• Certifications: UL1077/CSA C22.2 – No 235 / EN60947 – 2 & EN60934
• Common trip linkage between all poles. Another safety feature ensures that an overload in one pole will trip all adjacent poles.
